<Support Structure of Cowl Top Garnish>

A support structure of the cowl top garnish according to this embodiment will be described with reference to FIGS. 4, 5, 6A, 6B, 7A and 7B in addition to FIGS. 1A, 1B, 2 and 3.

FIG. 4 is an enlarged view of a portion F2 shown in FIG. 3. FIG. 5 is a view showing the support structure of the cowl top garnish according to this embodiment. FIGS. 6A and 6B are views each showing the structure of a cowl top-side engaging portion of the cowl top garnish according to this embodiment. FIG. 7A is an enlarged view of a portion F1 shown in FIG. 1A. FIG. 7B is an enlarged view showing a cowl top engagement bracket shown in FIG. 7A.

As shown in detail in FIG. 4, the shield glass fitting portion 64 of the cowl top garnish 6 includes a front wall portion 66 (second shield glass abutment portion) abutting against the shield glass front surface 7 b in the shield glass lower end portion 7 a, a rear wall portion 67 (first shield glass abutment portion) abutting against the shield glass back surface 7 c, and a back extended portion 68 that extends to connect each of the lower end portions of the front wall portion 66 and rear wall portion 67 in the vertical direction from the back surface of the surface portion 61 to the shield glass back surface 7 c, and is thus formed in a groove shape extending in the vehicle width direction. The rear wall portion 67 is provided to protrude from the back extended portion 68 along the shield glass back surface 7 c.

As shown in FIGS. 5, 6A and 6B, a cowl top-side engaging portion 30 that engages with a cowl top engagement bracket 20 (engaged portion) provided in the shield glass joint portion 42 of the upper end portion 4 a of the windshield lower panel 4 is provided on the back side of the shield glass fitting portion 64 in the cowl top garnish 6. The cowl top-side engaging portion 30 is provided to extend from the back extended portion 68 forming the shield glass fitting portion 64 of the cowl top garnish 6 to the rear side of the vehicle body. In the back extended portion 68, a drain hole 69 is formed adjacent to a portion as a side end portion in the vehicle width direction where the cowl top-side engaging portion 30 is provided. The drain hole 69 is provided to drain rainwater and the like flowing into the shield glass fitting portion 64 of the cowl top garnish 6.

A rectangular hole portion 21 is formed in the cowl top engagement bracket 20, and a wedge-shaped pawl portion 31 that engages with the hole portion 21 of the cowl top engagement bracket 20 is formed in the cowl top-side engaging portion 30. As shown in FIGS. 6A and 6B, the cowl top-side engaging portion 30 includes a pair of ribs 32 extending from the back extended portion 68 on the rear side with respect to the rear wall portion 67, and a bent portion 33 that bends and extends upward from the ribs 32, and the pawl portion 31 is formed in the bent portion 33. As shown in FIG. 4, the pawl portion 31 is provided at a position farther away from the shield glass back surface 7 c than the rear wall portion 67 abutting against the shield glass back surface 7 c in a direction perpendicular to the shield glass surface, and engages with the hole portion 21 of the cowl top engagement bracket 20 in a direction from the shield glass back surface 7 c to the shield glass front surface 7 b. At least one cowl top-side engaging portion 30 and at least one cowl top engagement bracket 20 are provided in the cowl top garnish 6 and the windshield lower panel 4, respectively (for example, a central portion in the vehicle width direction and both sides separated from the central portion by a predetermined distance). That is, the cowl top-side engaging portion 30 is provided in part of the shield glass fitting portion 64 of the cowl top garnish 6 in the vehicle width direction, and the front wall portion 66 and rear wall portion 67 of the cowl top garnish 6 occupy a range wider than that of the cowl top-side engaging portion 30 in the vehicle width direction in accordance with the shape of the shield glass lower end portion 7 a.

As shown in FIG. 4, a lip portion 66 a overlapping the shield glass front surface 7 b in the shield glass lower end portion 7 a is provided in the front wall portion 66 of the shield glass fitting portion 64 of the cowl top garnish 6. The lip portion 66 a has a shape curved toward the shield glass front surface 7 b, thereby allowing the distal end portion of the front wall portion 66 of the shield glass fitting portion 64 to be elastically deformed. In a state in which the shield glass back surface 7 c in the shield glass lower end portion 7 a abuts against the rear wall portion 67 of the shield glass fitting portion 64, a predetermined gap G1 is formed between the shield glass front surface 7 b and the back surface of the front wall portion 66. In the state in which the shield glass back surface 7 c abuts against the rear wall portion 67 of the shield glass fitting portion 64, a distance L1 between the rear wall portion 67 and an end portion 20 a of the cowl top engagement bracket 20 on the front side of the vehicle body is longer than the gap G1 between the shield glass front surface 7 b and the front wall portion 66. With this arrangement, the front wall portion 66 of the shield glass fitting portion 64 can be elastically deformed toward the shield glass front surface 7 b by the gap G1, and the pawl portion 31 of the cowl top-side engaging portion 30 can be detached from the hole portion 21 of the cowl top engagement bracket 20. In this case, if the front wall portion 66 of the shield glass fitting portion 64 of the cowl top garnish 6 is pressed toward the shield glass front surface 7 b of the windshield 7 to be elastically deformed, the pawl portion 31 of the cowl top-side engaging portion 30 moves in a normal direction perpendicular to the shield glass back surface 7 c, thereby canceling the engaging state with the hole portion 21 of the cowl top engagement bracket 20.

As shown in FIGS. 3 and 4, the windshield lower panel 4 to which the shield glass lower end portion 7 a is joined includes a panel main body portion 41 (vertical wall) extending toward the shield glass back surface 7 c, and a flat shield glass joint portion 42 extending upward from the panel main body portion 41 along the shield glass back surface 7 c. A portion between the shield glass back surface 7 c in the shield glass lower end portion 7 a and the shield glass joint portion 42 of the upper end portion 4 a of the windshield lower panel 4 is filled with an adhesive 11, and the shield glass back surface 7 c is joined while being sealed by a seal member 10 so the adhesive 11 does not flow to the lower side. In a state in which the seal member 10 is adhered to the shield glass back surface 7 c of the shield glass lower end portion 7 a, the windshield 7 is bonded to the shield glass joint portion 42 of the windshield lower panel 4 by the adhesive 11. The cowl top garnish 6 is attached after the windshield 7 is bonded to the windshield lower panel 4.

As shown in FIGS. 7A and 7B, the cowl top engagement bracket 20 is attached to the shield glass joint portion 42 separately from the windshield lower panel 4 by welding or the like to be located between the shield glass joint portion 42 and the shield glass back surface 7 c. The cowl top engagement bracket 20 has a size shorter than the shield glass joint portion 42 of the windshield lower panel 4 in the vehicle width direction along the shield glass lower end portion 7 a, and is partially provided in the shield glass joint portion 42. As indicated by a broken line 9 in FIGS. 7A and 7B, the shield glass back surface 7 c in the shield glass lower end portion 7 a is continuously bonded by the adhesive 11 in the vehicle width direction along the shield glass lower end portion 7 a across the cowl top engagement bracket 20 and the shield glass joint portion 42 of the windshield lower panel 4. As shown in FIG. 3 as well, the cowl top engagement bracket 20 includes a pair of rear extended portions 22 extending from the shield glass joint portion 42 to the rear side of the vehicle body, and an instrument panel 15 is attached to the rear extended portions 22 by a panel attaching bracket 16 provided in the rear extended portions 22 and a fastening member 17 such as a tapping screw.

In the above-described embodiment, when the rear wall portion 67 in the shield glass fitting portion 64 of the cowl top garnish 6 abuts against the shield glass back surface 7 c, the movement of the cowl top garnish 6 toward the shield glass front surface 7 b is suppressed. Thus, even if the cowl top garnish 6 is displaced toward the shield glass front surface 7 b, the cowl top garnish 6 is never detached since the cowl top garnish 6 moves in a direction such that the pawl portion 31 of the cowl top-side engaging portion 30 is not detached from the hole portion 21 of the cowl top engagement bracket 20. Therefore, it is possible to prevent the cowl top garnish 6 from floating from the shield glass lower end portion 7 a. When the rear wall portion 67 abutting against the shield glass back surface 7 c in the cowl top garnish 6 and the cowl top-side engaging portion 30 that engages the cowl top garnish 6 with the windshield lower panel 4 are provided separately so that the range where the cowl top-side engaging portion 30 is provided is narrower than that where the rear wall portion 67 is provided, degradation in assembly performance can be prevented. Furthermore, since a state in which the pawl portion 31 of the cowl top-side engaging portion 30 engages with the hole portion 21 of the cowl top engagement bracket 20 can be released only by pressing the cowl top garnish 6 toward the shield glass front surface 7 b, the maintainability is improved.

Since the rear wall portion 67 and the cowl top-side engaging portion 30 are formed in the back extended portion 68 of the shield glass fitting portion 64 of the cowl top garnish 6, the rigidity of each portion is improved. In addition, since a positional shift between the rear wall portion 67 and the cowl top-side engaging portion 30 can be suppressed, it is possible to reliably prevent floating of the cowl top garnish 6.

The state in which the pawl portion 31 of the cowl top-side engaging portion 30 engages with the hole portion 21 of the cowl top engagement bracket 20 can be canceled only by pressing the front wall portion 66 in the shield glass fitting portion 64 of the cowl top garnish 6 toward the shield glass front surface 7 b to be elastically deformed.

Even if the front wall portion 66 in the shield glass fitting portion 64 of the cowl top garnish 6 is pressed toward the shield glass front surface 7 b, the front wall portion 66 abuts against the windshield 7 first to receive the pressing force, and thus the rear wall portion 67 is prevented from abutting against the hole portion 21 of the cowl top engagement bracket 20, thereby preventing deformation of the hole portion 21 of the cowl top engagement bracket 20.

When the windshield lower panel 4 is provided with the shield glass joint portion 42 extending upward from the panel main body portion 41 along the shield glass back surface 7 c, deformation of the windshield lower panel 4 caused by pressing the windshield 7 toward the shield glass back surface 7 c can be prevented. In addition, since the shield glass joint portion 42 extends upward along the shield glass back surface 7 c, the engaged portion of the cowl top-side engaging portion 30 cannot be provided in the shield glass joint portion 42. Instead, by attaching the separate cowl top engagement bracket 20 to the shield glass joint portion 42, the cowl top-side engaging portion 30 can be engaged with the vehicle body.

When the windshield 7 is joined continuously in the vehicle width direction in a state in which the cowl top engagement bracket 20 is sandwiched between the windshield 7 and the shield glass joint portion 42 of the windshield lower panel 4, the attaching rigidity of the bracket 20 is improved.

When the instrument panel 15 is attached to the rear extended portions 22 of the cowl top engagement bracket 20, it is unnecessary to additionally provide a bracket for attaching the instrument panel 15, thereby making it possible to decrease the number of components.

Note that the above-described embodiment is merely an example for implementing the present invention, and the present invention is applicable to a revision or a modification of the embodiment without departing from the spirit and the scope of the present invention.

According to the first aspect, when the first abutment portion 67 abuts against the shield glass back surface 7 c, the movement of the cowl top garnish 6 toward the shield glass front surface 7 b is suppressed. Even if the cowl top garnish 6 is displaced toward the shield glass front surface 7 b, the cowl top garnish 6 is never detached since the cowl top garnish 6 moves in a direction such that the engaging portions 30 and 31 are not detached from the engaged portions 20 and 21. Therefore, it is possible to prevent the cowl top garnish 6 from floating from the shield glass lower end portion 7 a. When the first abutment portion 67 abutting against the shield glass back surface 7 c in the cowl top garnish 6 and the engaging portions 30 and 31 that engage the cowl top garnish 6 with the vehicle body are provided separately so that the range where the engaging portions 30 and 31 are provided is narrower than that where the first abutment portion 67 is provided, degradation in assembly performance can be prevented. Furthermore, since a state in which the engaging portions 30 and 31 engage with the engaged portions 20 and 21 can be canceled only by pressing the cowl top garnish 6 toward the shield glass front surface 7 b, the maintainability is improved.

<Second Aspect>

In the first aspect, the cowl top garnish 6 includes a surface portion 61 extending along the front surface 7 b of the windshield 7 and a back extended portion 68 extending in a direction from the surface portion 61 to the back surface 7 c of the windshield, and

the first shield glass abutment portion 67 and the engaging portions 30 and 31 are provided in the back extended portion 68.

According to the second aspect, the first abutment portion 67 and the engaging portions 30 and 31 are formed in the back extended portion 68 in the cowl top garnish 6, the rigidity of each portion is improved. Since a positional shift between the first abutment portion 67 and the engaging portions 30 and 31 can be suppressed, it is possible to reliably prevent floating of the cowl top garnish 6.

<Third Aspect>

In the second aspect, the surface portion 61 includes a second shield glass abutment portion 66 overlapping the front surface 7 b of the windshield 7, and

in a state in which the first shield glass abutment portion 67 abuts against the back surface 7 c of the windshield 7, a gap G1 is formed between the front surface 7 b of the windshield 7 and the second shield glass abutment portion 66.

According to the third aspect, it is possible to cancel the state in which the engaging portions 30 and 31 engage with the engaged portions 20 and 21 only by pressing the second abutment portions 66 in the cowl top garnish 6 toward the shield glass front surface 7 b to be elastically deformed.

<Fourth Aspect>

In the third aspect, in the state in which the first shield glass abutment portion 67 abuts against the back surface 7 c of the windshield 7, a distance L1 from the first shield glass abutment portion 67 to the engaged portions 20 and 21 is longer than the gap G1.

According to the fourth aspect, even if the second abutment portion 66 in the cowl top garnish 6 is pressed toward the shield glass front surface 7 b, the front wall portion 66 abuts against the windshield 7 first to receive the pressing force, and thus the first abutment portion 67 is prevented from abutting against the engaged portions 20 and 21, thereby preventing deformation of the engaged portions 20 and 21.

<Fifth Aspect>

In one of the first to fourth aspects, the vehicle body includes a windshield lower panel 4 attached with the windshield 7,

the windshield lower panel 4 includes a panel main body portion 41 extending toward the back surface 7 c of the windshield 7, and a shield glass joint portion 42 extending upward from the panel main body portion 41 along the back surface 7 c of the windshield,

the windshield 7 and a bracket 20 are attached to the shield glass joint portion 42, and

the engaged portion 21 is provided in the bracket 20.

According to the fifth aspect, when the windshield lower panel 4 is provided with the shield glass joint portion 42 extending upward from the panel main body portion 41 along the shield glass back surface 7 c, deformation of the windshield lower panel 4 caused by pressing the windshield 7 toward the shield glass back surface 7 c can be prevented. In addition, since the shield glass joint portion 42 extends upward along the shield glass back surface 7 c, the engaged portion of the engaging portion 30 cannot be provided in the shield glass joint portion 42. Instead, by attaching the separate cowl top engagement bracket 20 to the shield glass joint portion 42, the engaging portion 30 can be engaged with the vehicle body.

<Sixth Aspect>

In the fifth aspect, the bracket 20 is shorter than the shield glass joint portion 42 in a direction along the lower end portion 7 a of the windshield 7, and is arranged between the shield glass joint portion 42 and the back surface 7 c of the windshield 7, and

the windshield 7 is joined continuously across the shield glass joint portion 42 and the bracket 20.

According to the sixth aspect, when the windshield 7 is joined continuously in the vehicle width direction in a state in which the cowl top engagement bracket 20 is sandwiched between the windshield 7 and the shield glass joint portion 42 of the windshield lower panel 4, the attaching rigidity of the bracket 20 is improved.

<Seventh Aspect>

In the sixth aspect, the bracket 20 includes a rear extended portion 22 extending from the shield glass joint portion 42 to a rear side of the vehicle body, and

an instrument panel 15 is attached to the rear extended portion 22.

According to the seventh aspect, when the instrument panel 15 is attached to the rear extended portion 22 of the bracket 20, it is unnecessary to additionally provide a bracket for attaching the instrument panel 15, thereby making it possible to decrease the number of components.
